IPC: H01L33/08
Filed: 1984-09-03
Abstract: PURPOSE:To enable to change the wavelength of light to emit from a light-emitting element by a method wherein the element is constituted in such a structure that the directions of the currents to be impressed on the two semiconductor layers junctioned in a hetero-structure, which have the same conductive type and respectively have the forbidden band width different from each other, can be changed-over. CONSTITUTION:The semiconductor layer 4 on one side of the 6H-SiC semiconductor layers is made to epitaxially grow on a 6H-SiC substrate 3 and the semiconductor layer 5 on the other side of the 3C-SiC semiconductor layers is made to epitaxially grow on the layer 4. Wirings 1 and 3, by which positive voltage and negative voltage can be impressed on the light-emitting element by changing over, are provided. In this case, the wiring 1 is connected to an Ni layer 6 on the surface of the substrate 3 and the wiring 2 is connected to a mount 7, which is connected electrically with the layer 5 through an Ni layer 6. In this constitution, when positive voltage is impressed on the wiring 1 and negative voltage is impressed on the wiring 2, a blue light emission is seen. This is a light emission that corresponds to a transition between the forbidden bands of the 6H-SiC semiconductor layer. On the other hand, when negative voltage is impressed on the wiring 1 and positive voltage is impressed on the wiring 2, an orange light emission is seen. This is a light emission that the impurity in the 3C-SiC semiconductor layer is involved in the light emission.

Title: Take-up device for tape
Inventor: KOMORI TAKANAO
IPC: G11B15/30
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a control part by detecting wavelengths of signals changing in accordance with revolving speeds of respective hubs of a take-up and a supply and by changing over a take-up speed from a high speed to a normal speed when the difference between wavelengths reaches a predetermined reference value. SOLUTION: First and second photosensors 20, 22 transmit alternating signals whose revolving speeds are changed in accordance with revolving speeds of first and second hubs 24, 26 to a control part 16 by receiving reflected lights from black-and-white patterns of respective reflection plates 18 provided at first and second rotary shafts 10, 12. In a rewind operation, a motor 14 is revolved at a fixed high speed and a magnetic tape 30 is wound up from the second hub 26 to the first hub 24 with this motor. A control part 16 detects wavelengths of alternating signals from the first and second photosensors 20, 22 by respectively sampling them. Since the revolving speed is rised as the residual amount of the tape becomes smaller at the side of the second hub 26, the cycle of the alternating signal from the second photosensot 22 becomes shorter. Then, it is judged that the residual amount of the tape of the side of the second hub 26 became a few by the difference between the cycle from the sensors 22 and the cycle from the sensor 20.

Abstract: PURPOSE:To speed up a display system including the display controller. CONSTITUTION:According to instructions of a CPU 2, the display controller 1a writes data of a main memory 3, etc., in a display memory 4 and also reads data out of the display memory 4. At the time of the writing, the CPU 2 writes data in an R/W cache 100 and the display controller 1a writes the data, written in the R/W cache 100, in the display memory 4 in blanking periods. At the time of the reading, the CPU 2 reads data out of the R/W cache 100 or an R cache 200 when the target data are written in the R/W cache 100 or the R cache 200. Consequently, when the CPU 2 executes the read or write instruction for the display memory 4, limitations regarding a memory bus using are decreased, so the wait time of the instruction execution is shortened.

Abstract: PURPOSE:To reduce the floor area for installation of a facsimile device, by controlling in interlocking with both an open/close member of an original slit and a guide which changes the discharge position of recording paper, and using an original board also to a paper discharge tray. CONSTITUTION:In a reception mode of a facsimile device, a recording paper guide 10 has a displacement to discharge the recording paper 51 through the 1st discharge slit 8 to stack the paper on an original board 3. At the same time, an open/close member 5 is displaced to its closing position to prevent the paper 51 from dropping into an original insertion slit 4. In a transmission mode and a copying mode, the left edge part 5b of the member 5 is pressed with an operation hand to open the member 5. The inserted original is discharged through an original discharge slit 22. In a copy mode the paper 51 is discharged through a discharge slit 9 under the control of the guide 10. Thus the floor area for installation of a facsimile device can be reduced by an amount equivalent to a paper discharge tray excluded.

Title: Jig for heat treatment
Inventor: MATSUSHITA JUNICHI
IPC: H01L21/324
Filed: 1995-06-29
Abstract: PURPOSE: To make it possible to maintain a highly pure treating atmosphere by forming the whole jig out of single crystal silicon, and utilizing a dislocation formed in the single-crystal silicon to trap impurities, such as heavy metals. CONSTITUTION: A dislocation is formed in a furnace tube 4 made of single- crystal silicon, and impurities, such as heavy metals, are trapped by utilizing the dislocation: A dislocation layer 16 is formed in the inner portion of a furnace tube 4 of single-crystal silicon; the other portions are of dislocation-free crystal 15. As mentioned above, a dislocation layer 16 is formed in part of the surface of a jig for heat treatment so that impurities will be trapped in the dislocation layer 16. This virtually prevents process gas from reacting with the jig itself during heat treatment, which eliminates the possibility of reaction products containing moisture, for example, being produced.
